Hurst Diamond — cyclic diamond indicator

CycleSic cyclic indicator: multi-octave pivots (Half→32x) with confirmed diamonds, forming radar, and forecast — phasing handwriting on the pane.

On this page

Who this page is for — You turned on Hurst Diamond in CycleSic: it is a cyclic indicator (pane under price), not a freehand drawing. In two minutes you get confirm, radar, and forecast; deeper method links (phasing, synchronicity) sit below.

Sources: JM Hurst's Cycles Course (Cyclitec, ≈1973) and the Hickson / Sentient Trader tradition for diamond handwriting; Emiciclo harmonic grid and radar/forecast reading as in the CycleSic tool. The convention does not appear in the 1970 book.


In plain words

Hurst Diamond is an indicator: it reads cycles across octaves and writes on the pane where each duration turned (or is about to).

In phasing analysis, cycle lows (and, in later variants, highs) are dated on the chart. Classical handwriting puts a diamond under each trough; a stack of diamonds marks synchronized lows — the taller the stack, the longer the cycle that just turned.

In CycleSic that idea becomes a live tool: not only the mark on the past, but also the radar (an extreme still forming) and the forecast (where the model expects the next extreme on the same octave).

What you see on the pane

Mark Meaning
Filled diamond Confirmed pivot on that duration (Half, Full, 2x…)
Circle (radar) Extreme still forming — confirmation not closed yet
Forward diamond + zones Forecast: next-extreme projection and, if enabled, its range
Colored lanes One lane per octave — BarefootJoey color family

Pick Highs or Lows: the oscillator sits above or below zero so lanes stay readable. You can add two instances (e.g. Lows below + Highs above).


Harmonic grid (Nominal)

In Nominal mode, durations follow the ×2 Emiciclo-family progression (CycleSic defaults):

Lane Period (bars)
Half 16
Full 32
2x 64
4x 128
8x 256
16x 512
32x 1024

Dynamic scales the same grid to the timeframe’s dominant cycle: ratios stay; bar counts adapt.

Per lane you can toggle Label? (length label) and Forecast? (forward diamond/projection).


How to read it

  1. Choose Highs or Lows for what you are phasing (trough → Lows; crest → Highs).
  2. Read confirmations: filled diamonds say “this cycle turned here.”
  3. The radar warns that an extreme is under construction — not a verdict yet.
  4. The forecast extends timing expectations — not an automatic order.
  5. Compare octaves: a turn that shows on Full and 2x together weighs more than a lone Half (echo of synchronicity).

Worked sketch — On a timeframe whose dominant sits near 32 bars, Full is your anchor. If Full radar is live and the forecast lands near an FLD / VTL you already watch, you have cyclic-tool convergence — not a guarantee, but a coherent story.


Honest limits

  • A cyclic reading indicator, not a stand-alone buy/sell signal.
  • Nominal periods are a starting grid: markets with very different wavelengths may need Dynamic mode or hand-tuned periods.
  • Forecast is a model projection: bad underlying phasing → bad forward diamond.
